canon SD400 or SD450

[franz]

is there any notable difference between those two other than the larger lcd for the SD450? I don't really care for the larger lcd, so will I be happier with either (how about battery life or ISO settings?)

This is copy and paste from this site REVIEWS & INFO:
"Basically the SD400 with a larger LCD. Known as the IXUS 55 in some countries."
And yes, there is a notable difference. SD450 is pricier.
